EF 24-105mm f/4L IS USM

The second of Canon's professional-grade, f/4 L-series zooms – and in the eyes of some, the perfect standard zoom lens. On a full-frame camera, it covers the range from ultra-wide (24mm) through true portrait-length telephoto, at 105mm, and counters its slower f/4 aperture with Image Stabilization (allowing shutter speeds up to 3 stops slower than without IS). It's thus extremely practical for serious, critical shooters, whether for professional or business purposes, or for personal enjoyment by serious photo enthusiasts.

Combination of zoom range, Image Stabilization and sharpness makes this an ideal lens for many documentary users… from photojournalists to business and industrial users

Excellent for professional studio and event shooters, with a range covering most needs from large group photos to portraits

With its extended tele range, it's a great alternative for portraits, fashion and similar subjects to Canon's 24-70mm lenses
